Abstract
In a calendar book each page corresponds to a part of a month and is subdivided into a plurality of fragments corresponding to the different parts of the month. The fragments of a page are releasably secured to each other for ready separation. The separated fragments of the pages may be successively removed from the stack as time ensues for continuously revealing the current date and the successive dates next-following beyond the dates of the next-to-be-overturned fragment.
